You shouldn't have to wait for a week those results should be available in the next day or two your family dr. Should be able to access the results sooner if the ENT is out of town. Sorry you have to be here but it's a great place for support and information. Try not to worry. An MRI can light up many things (inflammation, scar tissue etc.. Even a benign growth ) ...usually a biopsy is a good thing to have since it's definitive. Push for one so you get an answer ASAP! Please keep us posted.. take care!
